Currency convert to symbol

[jrock2004]

Ok, unless I am misunderstanding, I would think I could pass in USD and it would return me the symbol. But its not

formatMoney(this.get('model.service.price.priceRange.min'), {
      symbol: this.get('model.service.price.currency'),
      precision: 2,
      thousand: "·",
      format: {
        pos: "%s %v",
        zero: "%s  --"
      }
    });```

Thoughts?
